For this, you can launch TransMac and click on the “Open Disk Image” icon in the toolbar. TransMac makes it very easy to access the contents of any DMG disk image. But if you want to both read the contents of an existing DMG file and create new disk images then you can try TransMac. But what if you want to access the contents of these DMG disk images from inside your Windows PC? You can use an old version of Aladdin Stuffit Expander (if you can still find it online) to extract the contents of DMG files. You can mount them in your Mac computer and read the contents easily.
These DMG files are actually disk image files supported only on Mac operating system. When you download software for your Mac computer, it usually comes in form of DMG files.
